  • Publication number: 20080229339
    Abstract: The present invention proposes a disc loading apparatus which has the ability to position either a large or small disc accurately against a turntable while improving miniaturization. A latching means having a first latch and a second latch are provided to feed and contact a disc against the common stopper by the loading motor power when either a large or small disc is inserted; when a large disc is inserted, the stopper means is latched against the first latch by moving the latching means to the position so as to avoid the latch of the second latch and the stopper means, and the disc loading detection means is loaded in the stopper means. This means moves the clamper to the position where a large or small disc is clamped in cooperation with the turntable by the movement of the driving means by receiving the loading motor power which moves to the stopper means by being pressed by the inserted large or small disc, and also separates the stopper from the disc when at least a large disc is loaded.

  • Patent number: 7299002
    Abstract: A fixer (heater) includes a heat roller and a pressure roller pressing each other. The fixer heats a heated material by passing the heated material through a press region where the heat roller and the pressure roller meet. The fixer further includes an external heat roller heating the pressure roller from outside the pressure roller. A transit time taken for any given point on the heated material to pass through the press region is less than or equal to 2.3×10?2 sec. The surface temperature, T1 (° C.), of the heat roller and the surface temperature, T2 (° C.), of the pressure roller satisfy T1-T2?100 (° C.), and preferably satisfy T1-T2?70 (° C.). The load on the heat roller is reduced, and so is the power consumption.
